L560 Touchpad/Trackpoint doesn't work

Hi. Suddenly touchpad stopped working. Did a windows reset, Bios update, all drivers update, disabled in bios then reboot. Every time i reboot i get code 24 error on ThinlPad ultranav device. It doesn't even work when i boot to windows pe or some other linux bootable cd. What am I doing wrong?

I have read that this is common problem on other models too. Some forums say that it maybe multiplexer failure on the board. I have tried to disconnect tochpad or trackpoint, from the board but the problem persists Smiley Sad

Hi ,

 

Check in Device manager, if driver is anywhere installed twice ( like synaptics touchpad/smb bus driver).

Disable and see if your tochpad works.

 

Regards

No. I have enabled hidden diveces and deleted all the drivers. Then installed official lenovo driver for alps touchpad. Drivers are useless because tochpad doesn't work on any bootable CD

Problem solved by 3rd party service (as we were told this notebook didn't have official warranty in our country) by swapping some capacitor and EC (embedded controller). Too bad lenovo didn't helped at all. Shame on You! Next time we will buy notebook from some other manufacturer.
